A coal/CBM database was implemented by the Alberta Geological Survey to capture and manage information related to coalbed methane (CBM). The database is a compilation of data from many different sources and contains information on 7923 wells (15,200 formation picks; 37,357 coal picks; 495 coal analyses; and 363 vitrinite reflectance measurements). This is a subset of those wells that fall inside the coal zone.
Natural gas plays a key role in our nation’s clean energy future. Recent advances in drilling technologies—including horizontal drilling and hydraulic fracturing—have made vast reserves of natural gas economically recoverable in the US. Responsible development of America’s oil and gas resources offers important economic, energy security, and environmental benefits. Hydraulic fracturing is a well stimulation technique used to maximize production of oil and natural gas in unconventional reservoirs, such as shale, coalbeds, and tight sands. During hydraulic fracturing, specially engineered fluids containing chemical additives and proppant are pumped under high pressure into the well to create and hold open fractures...
Coalbed methane is one of the most important and valuable natural resources in the Western United States. The natural gas that results from CBM development is the cleanest burning fossil fuel, and the extensive domestic supply makes it a central element of the national goal of a secure supply of energy. Demand for natural gas will continue to grow and CBM will play an increasingly larger role in meeting that demand. CBM production has expanded tremendously over the past decade, and the rapidity with which development has expanded has resulted in stresses and tension in affected communities. Development of this important energy resource must be balanced with a number of other important goals of protecting water,...
Federally owned and managed public lands occupy approximately 30 percent of the land area of the United States, and anywhere from 50 percent to more than 80 percent of the land area of many of the western states. Determining the appropriate use of these lands involves balancing objectives related to economic, recreational, and conservation interests. This paper examines established and emerging conflicts within and across these objectives through both a narrative discussion of specific topics and a series of case studies. The authors find that new challenges, including pressures to devote portions of public lands to renewable energy project development and the multifaceted threats presented by climate change, will...
Coalbed methane has rapidly become an important source of natural gas, particularly in the Intermountain West. The rapidity of its development has resulted in significant pressure on communities to deal with its environmental consequences. Coalbed methane production often results in large quantities of water that are released as byproducts of production; in some cases, the water may inundate sensitive arid ecosystems, worsen surface water quality, and diminish underground water supplies. Noise, dust, and increased traffic; impairment of visibility and conflicts with recreation and other land use; impacts on wildlife and ecosystems; and other consequences of development have generated opposition in many communities....

The Alaska Geologic Materials Center (GMC) in Eagle River holds non-proprietary rock core and cuttings that represent over 13 million feet of exploration and production drilling in Alaska. Additionally, the collection holds more than 252,000 linear feet of diamond-drilled hard-rock mineral core, representing more than 1,800 exploratory boreholes; 76,000 linear feet of oil and gas core and rock samples from more than 1,650 exploratory or production wells; samples for geotechnical boreholes; and numerous surface rock and sediment samples. The collection also includes extensive geochemical data and processed material derived from this rock. This publication represents the GMC inventory in accessible, intuitive digital...
In 2002, the U.S. Geological Survey (USGS) assessed the technically recoverable, undiscovered coalbed-gas resources in the Appalachian basin and Black Warrior basin Assessment Provinces as about 15.5 trillion cubic feet. Although these resources are almost equally divided between the two areas, most of the production occurs within relatively small areas within these Provinces, where local geological and geochemical attributes have resulted in the generation and retention of large amounts of methane within the coal beds and have enhanced the producibility of the gas from the coal. In the Appalachian basin, coalbed methane (CBM) tests are commonly commercial where the cumulative coal thickness completed in wells is...

Abstract: Coalbed methane (CBM) development raises serious environmental concerns. In response, concerted efforts have been made to collect chemistry, salinity, and sodicity data on CBM produced water. However, little information on changes of stream water quality resulting from directly and/or indirectly received CBM produced water is available in the literature. The objective of this study was to examine changes instream water quality, particularly sodicity and salinity, due to CBM development in the Powder River watershed, which is located in the Rocky Mountain Region and traverses the states of Wyoming and Montana. To this end, a retrospective analysis of water quality trends and patterns was conducted using...

The southwest states of Arizona and New Mexico are energy rich, particularly New Mexico. Data is presented establishing the reigions position with respect to coal, oil, gas and uranium resources. Further, this status is reflected in current patterns of energy production, data on which are presented. Additionally, price information is presented which explains, in part, current energy production patterns in the region.
Lignite and subbituminous coals were investigated for their ability to support microbial methane production in laboratory incubations. Results show that naturally-occurring microorganisms associated with the coals produced substantial quantities of methane, although the factors influencing this process were variable among different samples tested. Methanogenic microbes in two coals from the Powder River Basin, Wyoming, USA, produced 140.5–374.6 mL CH4/kg ((4.5–12.0 standard cubic feet (scf)/ton) in response to an amendment of H2/CO2. The addition of high concentrations (5–10 mM) of acetate did not support substantive methane production under the laboratory conditions. However, acetate accumulated in control incubations...

This feature class was created to assemble oil and gas well information for a comprehensive inventory of energy data pertinent to the Wyoming Landscape Conservation Initiative decision-making process. These data are available as online resources for scientists, resource managers engaged in the Initiative, and other researchers. The GIS data and map services created for this study are available for interactive analysis and/or download at the Energy Geoscience Center WLCI website.

The Coalbed Methane-Demineralization Treatment Cost (CBM-DTC) toolbox has been developed to predict the costs associated with treating Powder River Basin (PRB) coalbed methane (CBM) waters based on influent water characteristics, effluent water requirements, and the capabilities of selected technologies. The costs predicted by the toolbox should not be considered to be the exact costs, but approximations.

This dataset is field boundary polygons of Coalbed Methane (CBM) based on producing wells in the USA. Field outline polygons were created by buffering wells from each field. Buffered well polygons from each field were then unioned into a single polygon record (may contain multiple rings). A smoothing algorithm was applied to the polygons. Features are colored by Basin. Fields are coded with Geologic Ages, Formations, and Coal Names. Age Codes are Exxon Mobil Age Codes.

Coalbed Methane (CBM) proved reserves and cumulative production by coal basin in the United States. Proved reserves are from the Energy Information Administration's (EIA) U.S. Crude Oil, Natural Gas, and Natural Gas Liquids Reserves, 2006 Annual Report. Proved reserves are the quantities of gas that geologic and engineering data demonstrate with reasonable certainty to be recoverable in future years from known reservoirs under existing economic and operating conditions. The absolute values of proved CBM reserves for the Wind River, Forest City and Illinois basins cannot be released for reasons of confidentiality. The absolute values of proved CBM reserves for the Piceance and Gulf Coast basins are not released due...
